Yes, removing the qualify may have a big effect within the script and all the UI dimensions/expressions and the resulting efforts to adjust everything might be really huge and even greater as re-creating the application from the scratch. Nevertheless I suggest to consider the last very carefully because maintaining a bad designed application could become a bigger nightmare as starting at the beginning again by applying all learnt things from the last months/years ...
In your special case you may directly before this load set an:
unqualify *;
and afterwards you enables it again with:
qualify *; // respectively with those fields which should be regarded for it
